Glad to hear that you are enjoying that high quality tactical torch mikebosmans, it is a major torch for sure!
When light from all parts of the visible spectrum overlap one another, the additive mixture of colors appears white to your eye. However, your eye does not require a mixture of all the colors of the spectrum to perceive white light. Primary colors from the upper, middle, and lower parts of the spectrum (red, green, and blue), when combined, appear white.
The reason the white CREE XML LED in the Olight M3-X (or any other white led light for that matter) not putting out much from the ground glass red filter is that the filter is blocking all the other lightwaves put out by the LED except the red wavelength. White LEDs as a rule do not put out much in the red wavelength range. So with the red filter you are blocking the majority of the light output from the LED.
They DO put out quite a bit of green wavelengths however as you can easily see!
Each different white LED of different BIN number puts out different specific light wavelengths, each LED is going to be different, but basically most are weak in the red wavelengths.
If you need a dedicated red beam, it is best to use a red led light like the KLR-250 or the Olight M-20 Crimson that puts out primarily red wavelengths only.
